THEODORE AHRENS, OF LOUISVILLE, KENTUCKY.

IMPROVEMENT IN PRESERVING AND DELIVERING BEER, ALE, &c., 0N DRAFT, BYMEANS 0F CARBONIC- ACID GAS.

Specification forming part of Letters Patent No. 106,019, dated August2, 1870.

To all whom 'it may concern:

Be it known that I, THEoDoRE AHRENs, of Louisville, in the county ofJefferson and State of Kentucky, have invented certain new and usefulImprovements in Device and Process for Forcing Liquids ContainingCarbonio-Acid Gas up to any desired' height; and I do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawing, and to the letters ofreference marked thereon, which form a part of this specification.

The nature of .my invention consists in the construction and arrangementof an apparatus for keeping any liquid containing carbonio acid fresh,and when said liquid is kept in cellars to force it up into a roomabove.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-A represents cylinder or other suitable vessel to contain marble-dust,above which by suitable means is supported another cylinder, B,containing inuriatic acid. C is still another cylinder, placed a shortdistance from the former, andk filled about one-third full of water, soas to purify the carbonio acid as it flows in the top of said cylinderto the vessel cont Iiniug the liquid. A pipe, G, connects the cylindersA and B, and another pipe, H, runs from the cylinder A to a pipe, I,which runs up in the cylinder B above the muriatic-acid line.

The pipe G is provided with a clamp, a., and as soon as these clamps areloosened the air containedin the cylinder A will pass up into B, and themuriatic acid in B will flow into A, where it will transform intocarbonio acid and pass through a pipe, J, from the top of the cylinder Ainto the cylinder C, near its bottom, where it becomes purified bypassing throughthe water contained therein. Thence the carbonio acidpasses through the pipe E into the vessel containing the liquid, keepingthe liquid fresh, and at the same time forcin the liquid up to anydesired height.

The cylinders A and B are lined with sheetlead, to keep the acid fromcorroding them.

Near the bottom of the cylinder C is an opening and pipe, K, forcleaning the cylinder when necessary, and on top of said cylinder is asafety-valve, b, to prevent getting too much pressure.

The pipes J and K are also provided with clamps the same as the pipe G.All three of said pipes being ilexible the clamps can entirely closethem, which is a cheaper and far more durable method than the usualstopcocks.

l am aware that carbonio-acid gas has been used in various manners forpreserving beer and other liquids, and I do therefore lay no claim tosuch as my invention, my object being mainly to force such liquids up tothe desired height by means of pressure caused by carbonio-acid gas.vFor instance, beer may be kept in the cellar, and by allowingcarbonicacid gas, under a certain pressure, to enter the keg, it may beforced up to the first, second, or third story to be served out. Thepressure Aof the gas is regulated iu the tank C, the gage D showing atall times if the necessary amount Y of pressure is kept up. from thecylinder A. On the cylinder C is a A pressure-gage, D, and a pipe, E,leading from Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

\l. The method herein described of forcing beer or other liquids up toany desired height by means of carbonio-acid gas, as set forth.

2. The arrangement of the cylinders A B (l, pipes E G H J K, clamps a a,gage D, and valve b, for the purposex of forcing beer or other liquidsup to any desired height by means of carbonicacid gas, substantially asspecified.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
